Description: Predictive direct power control (P-DPC) applied
to voltage source pulse-width-modulation (PWM) rectifier was
introduced in this paper. Based on the model of power
prediction, voltage vectors were selected according to
minimizing power errors in a fixed time interval, which results
in a constant switching frequency control for P-DPC. It
simplifies the implementation of P-DPC procedure by selecting
switching states based on the principle of space vector
modulation (SVM). In order to eliminate power errors caused
by control delay, a detailed control delay compensation scheme
was designed. Experimental results based on a 2kW prototype
were presented, which showing that P-DPC has a faster power
response compared to standard voltage-oriented-control (VOC)
techniques. Besides, the dynamic performance of the system is
also improved significantly by control delay compensation.
